Surgical intervention
Endoscopy-assisted laparoscopic intragastric resection of early gastric cancer
In the minimally invasive approach to a gastric pathology, the association of laparoscopy with endoscopy (also called hybrid or collaborative surgery) emerges as an advanced therapeutic option for the surgical treatment of both benign and malignant intragastric lesions in selected patients.
We present the case of an elderly patient aged 86 with a serious medical history. She is endoscopically diagnosed with a gastric lesion located in the incisura angularis with a biopsy of high-grade dysplasia/carcinoma “in situ”.
Given the patient's age and her medical history, the multidisciplinary committee decided to perform a minimally invasive surgery. Submucosal dissection of the lesion using a hybrid approach (intragastric endoscopy/laparoscopy) was proposed.
The pathological area was marked and stained by endoscopy, followed by intragastric submucosal dissection with laparoscopic instruments assisted by means of endoscopy.
The surgery went smoothly and the patient could be discharged 48 hours after surgery.
Final pathological findings reported a well-differentiated tubular adenocarcinoma infiltrating the lamina propria and surgical resection margins free of tumor infiltration (pT1a Nx Mx (TNM 8th Ed. 2017)).

Endoscopic sleeve gastroplasty (ESG): live educational procedure with resolution of device-related complication
Endoscopic sleeve gastroplasty (ESG) is a novel endobariatric procedure with a mechanism of action totally different from the one used for a standard sleeve gastrectomy. An over-the-scope suturing system (OverStitch™, Apollo Endosurgery, Austin, TX) mounted on a dual-channel gastroscope (GIF- 2TH180, Olympus, Center Valley, PA) allowed to place full-thickness sutures in order to obtain gastric volume reduction and shrinking. The number of applied sutures relies on the gastric volume. Sutures are placed starting from the incisura to the fundus that is spared in a U-shaped fashion. A tissue-retracting helix device is used to grab the gastric wall. In this live educational video, Professor Silvana Perretta presented the case of a morbidly obese 38-year-old female patient with a BMI of 36.72kg/m2.
The procedure was performed with the patient under general anesthesia and carbon dioxide insufflation. An Overtube™ (Apollo Endosurgery, Austin, TX) was placed at the beginning of the procedure to protect the airways, the esophagus, and the hypopharynx. Each purse-string suture consisted of 6 to 8 full-thickness bites starting first on the anterior gastric wall, then on the greater curvature, and the posterior wall and moving backward in the opposite direction. Once completed, the suture was tied and knotted using a cinching device (EndoCinch™). During the live procedure, a complication occurred due to an excessive pressure placed on the EndoCinch™ handle which caused a break of the collar part of the cinch. The management of this complication was achieved by cutting the suture, so that the collar part of the cinch which grasped the mucosa could be detached with a grasper to allow for suture replacement. A total of 4 sutures were applied in order to obtain gastric tubulization.
